Bash script failing with unknown option due to space in argument

问题

I am trying to run aws create lambda function. It goes as follows -

eval $(aws lambda create-function \
--function-name $FUNCTION_NAME \
--runtime $RUNTIME \
--role $ROLE \
--handler $HANDLER \
--region $REGION \
--zip-file $ZIP_FILE \
--profile $PROFILE \
--environment $env_variables)

All the variables come from command line. It is failing for env_variables. This gets constructed as -

env_variables="Variables={INPUT=${DAYS}}"

where DAYS is actually "20 days"

How can I avoid this space and pass my command successfully.

回答1:

The value needs to be wrapped in quotes, try this:

env_variables="Variables=\"{INPUT=${DAYS}}\""

回答2:

Finally following worked -

env_variables="\"Variables\":{\"INPUT\":\"${DAYS}\"}"

lambda_create_command="aws lambda create-function --function-name $FUNCTION_NAME --runtime $RUNTIME --role $ROLE --handler $HANDLER --region $REGION --zip-file $ZIP_FILE --profile $PROFILE --environment '$env_variables'"

echo "Executing command : $lambda_create_command"

eval $lambda_create_command
